A type of deism that combines the belief in a rationally determined, non-interfering God with the idea of pantheism that God is the same as the Universe with the idea of deism that God is revealed by rational examination and does not interfere with the Universe.

Combines deism and pantheism to propose a deistic God that turns into a pantheistic universe. This term was first used by Moritz Lazarus and Heymann Steinthal in the journal Zeitschrift für Volkerpsychologie und Sprachwissenschaft (1859).
